reconstruction life-threatening. After the earthquake, the highways were initially covered by loose soil de-posits of landslides, and subsequently exposed to frequent landslide hazard chains in the forms of rock falls, rain-induced landslides, debris flows, landslide damming and flooding. The success of the reconstruction pro-jects depends on the degree of landslide risk mitigation.

‘Group photo’ of the lecture

Significant efforts were made to understand landslide hazard chains along the highways, particularly inter-actions between separate hazards in each chain, and their evolution over time (Fig. 2). Fatal hazard sce-narios could be missed in design if such interaction effects are not considered. Dr. Zhang emphasized the importance of the lifecycle concept in assessing risks of landslide hazard chains. It is necessary to investigate each individual hazard over its lifecycle from the formation of the hazard to the cessation of further evolu-tion; for instance from the formation of a landslide deposit to the cessation of reactivation and erosion in the deposit, or from sedimentation to the incision of a stream, and to investigate each hazard over the space the hazard evolves over its lifecycle. Dr. Zhang went on to present a quantitative framework for multi-hazard risk assessment to evaluate the risks posed by cascading landslide hazards considering the interactions among various hazards and the pos-sible cascading effects on human vulnerability. The framework, known as the HKUST five-phase method, consists of five major steps: definition of time and space scales, multi-hazard assessment, exposure assess-ment, multi-vulnerability assessment, and multi- risk assessment. Finally, Dr. Zhang described how risk-informed decisions were made in the design and selection of highway alignment options and engineering risk mitigation measures. To mitigate the risks, all three major compo-nents of engineering risk, e.g., probability of failure, vulnerability and element at risk, will have to

be addressed, as shown in Fig. 3. Taking engineering measures to stabilize the slopes alone is not viable in such deep valley environment in Fig. 1. The quantitative risk assessment resulted in a significant reduction (to about 20% and 33% of the initial risk levels for Highways S303 and G213, respectively) in potential loss of life through the use of long tunnels to bypass the high-risk landslide zones and protective measures which respond more effectively to manageable, smaller scale hazards. Today, the approach of risk-informed land-slide hazard mitigation has influenced and become routine practice in the design and construction of high-ways in the seismic mountainous region of western China.

Abstract: In spite of the advances in the field of earthquake engineering, economic losses left by large recent earth-quakes are still considerable, far from any socio-economically satisfactory standard. According to the Chil-ean experience, a crucial factor that govern the resulting seismic damages is associated with the local ground conditions. Therefore, a key issue in the seismic regulations is an appropriate seismic site classifica-tions. An alternative seismic site classification has been proposed in Chile, which incorporates two important dynamic parameters of the ground: the classical shear wave velocity, VS30, and the predominant period of the soil deposit, which is estimated via the H/V spectral ratio of ambient vibrations, or Nakamura´s proce-dure. The site classification first uses the VS30, and then the class has to be corroborated by the predominant period of the site.

1. Introduction Unfortunately, societies around the world continue to suffer significant economic losses and victims due to large and medium earthquakes. An important part of these losses and casualties is attributed to the severe damages experienced by buildings (residential, commercial, governmental, educational, cultural, hospital, etc.), infrastructure and industrial structures. Therefore, in spite of the tremendous advances in the field of earthquake engineering, economic losses are still considerable far from any socio-economically satisfac-tory standard. Furthermore, it is important to understand that modern society not only wants protection of life, but also it demands that buildings can be occupied and function after a strong earthquake. This also means that water, electricity, gas, and other services have to be operational as well. Therefore, the chal-lenge is to reduce the tremendous economic impact that earthquakes still have on the community, and accordingly, resilience and reliability of structures is an important issue (Cimellaro, 2017). In order to achieve a better seismic behavior of the structures, among other factors, it is necessary to identify the ground conditions that govern the seismic loads that will be induced to the structures. The effect of local soil conditions on ground surface motions has been widely recognized from both theoretical and empirical points of view. An example of this has been observed in the recent large earthquakes that have hit Chile, where, in general, an excellent performance of the structures was observed. However, there were exceptions that are mainly attributed to a deficient site characterization. Accordingly, the country was forced to development a more efficient seismic site classification, which is briefly explained in this article.

2. Historical evidence of seismic amplification Systematically, large earthquakes has shown that the intensity of the motion developed at the ground sur-face is strongly controlled by both the geotechnical characteristics and thickness of the sediments. A re-markable case of amplification is the one observed during the 1985 Mexico City earthquake of Magnitude 8.1, where the shaking was amplified by a factor of 20, or even more, on sites constituted by deep soil deposits of soft fines materials (Celebi et al. 1987; Singh et al. 1988). On the other hand, rock outcrops and stiff soil deposits have shown a significant reduction in the shaking intensity (Montessus de Ballore, 1911; Watanabe et al. 1960; Borcherdt, 1970; Seed et al. 1988). An important Chilean experience that showed the site effect took place in the 1906 Valparaiso Earthquake of Magnitude 8.2. This strong ground motion occurred approximately 4 months after the San Francisco Earthquake, where similar site effects were ob-served (Borcherdt et al. 1976). In Fig. 1 is shown the general geology of Valparaíso, which basically consist on a massive rock outcrop of the Coastal Range and a rather small flat area constituted mainly by medium to dense sandy soils. A borehole performed near to the National Congress (Fig. 2) found the bedrock at a depth of 57 m.

et al. 2010) Figure 2. Location of buildings with and without

Among the few buildings that underwent minor damages during the 1906 Valparaiso Earthquake are Aduana and Palacio Lyon. The Aduana building is founded on rock outcrop and Palacio Lyon is founded only few meters above the bedrock. These two historical buildings still exist today as shown the photos of Fig. 3, which means that they have responded appropriately to the series of shaking that have occurred in the area after their construction: Valparaiso 1906 (M = 8.2); 1985 (Mw = 8.0) and 2010 (Mw = 8.8).

On the other hand, a severe destruction of buildings located in the soil deposit was reported. Two emblem-atic buildings: Theater Victoria, built in 1886 (Figs. 2 and 4), and La Merced Church, built in 1893 (Fig. 2), collapsed during the 1906 Earthquake.

After the effects of the 1906 Earthquake, Henriquez (1907) and Montessus de Ballore (1911) concluded that geological conditions are fundamental in the observed damages. They reported that buildings placed on soils deposits presented heavy damage, while constructions placed on the hills (rock outcrop) experienced no damage or it was negligible. This is confirmed in the photo of refugees of Fig. 5, where in the hilly area there are undamaged buildings that amazingly remained after the earthquake. Conversely, the photos of Fig. 6 expose the total destruction that took place in the area of sandy soil deposits (no evidence of lique-faction was reported). This important lesson of significantly better seismic performance of structures founded on rock or competent soils has been systematically observed in large earthquakes.

Figure 5. Hilly area, undamaged buildings. Figure 6. Heavy destruction, soil site

Empirical and theoretical observations suggest that the intensity of ground surface motion strongly depends on the site characteristics such as soil type, soil properties, as well as the thickness of the soil deposit (Montessus de Ballore 1911, Seed et al, 1976, Pitilakis et al, 1998, among many others). On one hand, the evidence indicates that, after large earthquakes, sites with rock outcrops or stiff soil present limited or null damage in structures placed on this type of ground. On the other hand, significant damage is observed on sites consisting of deep deposits of soft soils (Borcherdt 1970; Seed et al., 1988, Singh et al. 1988). Never-theless, it is important to recognize that soil sites tend to amplify the shaking at low frequencies (high period), but rock sites tend to have more intensity at high frequencies (low periods). Thus, the Chilean and international experience is that, site conditions determine the motion at the ground surface, in addition to the characteristics of the seismic sources/mechanisms.

3. Design spectra, site effects and seismic hazard In seismic countries, all structures must be designed to withstand the dynamic disturbances generated by earthquakes. For ordinary structures, seismic loads can be computed using the modal spectral analysis, where the seismic demand is characterized through a design spectrum. The particular ground conditions can drastically modify both the shape and amplitude of the design spectrum. Because of this, the design spectra are defined as function of the site characteristics.

The seismic provisions available worldwide have established a Soil Class classification taking into account the soil properties of the upper 30 m of the ground, regardless of the actual thickness of the soil deposits and properties of the existing soils below a depth of 30 m. This simplification can lead to significant errors in the evaluation of the main characteristics of the seismic response at the ground surface. Consequently, for a rational site characterization, it is imperative to include a parameter that allows obtaining relevant information associated with the seismic response of the entire soil deposit. For fairly flat ground conditions, and from the point of view of wave propagation, it results evident that strength parameters are not really suitable to evaluate the seismic amplification. However, parameters associated with the soil strength as N-SPT or unconfined resistance are usually considered by the codes to evaluate the seismic site classification. However, from a theoretical point of view, the site amplification is mainly controlled by soil stiffness, sequence of soil layers, thickness of the soil deposit, dumping, impedance (sediments-bedrock). Therefore, a site classification should be based primarily on parameters associated with the dynamic response and leave out resistance parameters. Besides the site effect, another important issue is the level of seismic hazard to consider, which is associated with the recurrence interval and corresponding probability of occurrence. It is interesting to point out that most of the existing seismic codes are based on probabilistic or deterministic seismic hazard analyses. The EC8 applied a probabilistic analysis approach, whereas the Japanese codes are based on a deterministic seismic hazard analysis. USA represents a singular case, where both approaches have been applied, and the maximum credible earthquake ground motion for a site is selected as the lesser output from these two analyses. The probabilistic and deterministic methods for the assessment of seismic hazard are usually pre-sented as antagonistic approaches. However, they may certainly complement each other for estimating the ground motions for design. In regions where continental active faults and/or tectonic boundaries generate the largest seismic events expected to occur every 100-200 years, the deterministic seismic hazard analysis is more suitable, providing valuable empirical information about the ground motion. It is possible to indicate that the present Chilean code is also based in a combination of both probabilistic and deterministic methods.

4. Brief synthesis of Chilean seismicity The seismic activity of Chile is mainly the result of the subductive seismic environment generated by the collision between the Nazca and South American tectonic plates, which are converging at an estimated rate of 65 to 80 mm per year. The Nazca plate is subducting under the South American plate, moving down and landward. Accordingly, four types of seismic mechanisms in the Chilean subductive seismic environment can be identified: outer rise (outside trench, in the bending zone of the Nazca Plate), interplate or thrust-faulting type that occurred on the interface between the plates, intraplate that take place inside the Nazca Plate, and cortical (faults on the South American Plate). From an engineering point of view, the most im-portant earthquakes are the interplates of large magnitudes. Although the intraplates and corticals are important too, their severe effect is restricted to a rather limited zone close to the epicenter. Therefore, in the practice intraplate earthquakes are those considered by Chilean seismic codes. In Fig. 7 are summarized the earthquakes of magnitude greater than 7.5 that have struck the country since 1906. It is interesting to observe that the high seismic activity of Chile is reflected by the presence of two large events in the list of the top 10 world earthquake: the top 1 (Valdivia Earthquake) and the top 6 (Maule Earthquake). The most recent large interplate earthquake that hit the country is the Maule earthquake, of moment mag-nitude Mw = 8.8. It is the sixth largest seismic event instrumentally recorded in the world. It struck the south-central part of Chile on February 27th, 2010 (3:34 am local time). It compromised a rupture area at the interface between the plates, at an average depth of 35 km, with an approximately rectangular zone, of 550 km long and 170 km wide.

Figure 7.- Chilean earthquakes of M ≥ 7.5 since 1906 (Valenzuela et al 2020) The fundamental implication of the large rupture zone involved in a mega-earthquake is associated with the obsolescence of the usual concept of hypocenter, which is commonly seen as a point from where the seismic energy is generated, and from where the attenuation of the shaking with the distance is evaluated. Mega-earthquakes present an extensive zone from where the seismic energy is released. From this perspec-tive, near to this zone, the attenuation is significantly less relevant than the site amplification due to local characteristics of soil deposits. The horizontal peak ground accelerations recorded on rock outcrops and soil deposits are indicated in Fig. 8 (the rectangular area corresponds to the rupture zone of these mega-earthquake). These records show that the common expected attenuation of the peak accelerations with the distance is not observed. In this context, it is interesting that the largest peak acceleration of the ground, 0.94g, was recorded in Angol, located to the south of the rupture, whereas the second largest peak acceleration, 0.78g, was recorded in Melipilla, to the north of the rupture, while in Talca, located between the previous two stations, the hori-zontal peak acceleration reached a value of 0.47g. In any case, away from the rupture zone, the seismolog-ical theory and observations indicating that ground motion intensity decreases with increasing distance from the source hold valid.

5. Amplification: key parameters that can be measured From a theoretical perspective, the parameters that govern the phenomenon of amplification of seismic waves in a soil deposits are reasonably well known. However, for practical purposes most of them are diffi-cult to obtain due to cost and time limitations. Therefore, it is necessary to use key parameters that can actually be measured in practice. Accepting that a soil deposit has a fundamental period of vibration, identified by the maximum amplification of the transfer function (ratio between Fourier spectra of ground surface to bedrock), the question is whether the Nakamura, or H/V spectral ratio (HVSR) procedure using ambient vibration can capture this predominant period. Measurements carried out on sites where seismic stations recorded recent large earth-quakes in Chile confirmed that the HVSR provides a robust procedure to evaluate the predominant period of a site (Verdugo et al 2016). In Fig. 9 are presented the different types of HVSR depending on the site conditions. When a clear peak is observed, the site corresponds to a soft soil deposit with medium to large values of predominant period. On the contrary, flat curves of HVSR are observed in stiff soil deposits, where a clear predominant period does not exist, and a wide range of periods (or frequencies) are amplified. This important result makes possible the identification of those sites that are not conflicted from the point of view of their seismic response. Additionally, it allows evaluation of the predominant periods of soft sites, which are sites that can be problematic.

On the other hand, the upper 30 m of a site represents the crust that is also important in the amplification of the motion resulting at the surface. Therefore, the classical parameter, VS30, which reproduces the vertical travel time of the shear wave propagating throughout the top 30 m of the ground is also suitable for characterizing a site from its dynamic response at the surface.

6. Seismic site classification proposed in Chile It is important to keep in mind that during large earthquakes, rigid soil deposits, such as rock outcrops, cemented soils or very dense gravels, have shown negligible, or no damages on structures. On the contrary, soft soil deposits, as for example, the clayey material of Mexico City, or the bay mud of San Francisco, or the sandy soils of Valparaíso, have shown a dramatic number of damaged structures as well as fully collapsed ones. This means that the classification goes from good sites to complex sites where high amplification and potential damages are expected. In this scenario, the proposed site classification considers that the VS30 is the fundamental parameter, but it has to be corroborated, or verified, by the predominant period obtained via ambient vibrations using the HVSR procedure. If the predominant period does not confirm the site class, then the site classification is degraded in on step. Accordingly, the proposed site classification in Chile is summarized in Table No. 1.

Table 1. Site Classification

The proposed classification is the result of long discussions and meetings where several Chilean engineers, practitioners and academicians, interacted looking for a better and safer code.

Major project


1. Introduction Africa faces a pronounced infrastructural deficit when compared to most developed countries and regions. Therefore, both innovative and sustainable infrastructure is crucial for Africa’s economic integration. As such, the vision of advancing geotechnics in Africa is a positive notion directed at the development of the continent. In this context, the main theme of the Seventeenth African Regional Conference on Soil Mechan-ics and Geotechnical Engineering (17th ARCSMGE), held at Century City Conference Centre in Cape Town, South Africa, from 7th to 9th October 2019, “Innovation and Sustainability in Geotechnics for Developing Africa”, was most appropriate and timely. The scope was broad and inclusive, presenting a range of oppor-tunities to stakeholders from the entire geotechnical community.

The 17th African Regional Conference on Soil Mechanics and

Geotechnical Engineering held in Cape Town, South Africa

Organised in the scenic city of Cape Town by the South African Institution of Civil Engineering’s Geotechnical Division (SAICE), and in conjunction with the International Society of Soil Mechanics and Geotechnical Engi-neering (ISSMGE), this prestigious event brought together academics and practitioners from across the globe. The SAICE Geotechnical Division is the largest geotechnical society in Africa with a membership of 880 individuals, which is approximately 69% of Africa’s 1,289 members of the international society. The host city, Cape Town, a major port city located on South Africa’s southwest coast, is richly endowed with remarkable beaches, sunshine, a peninsula beneath the imposing Table Mountain, a busy harbour in-cluding boats heading for Robben Island (the notorious prison where Nelson Mandela was held for 27 years) and wonderful people. All of which make this city and the surrounding areas, one of the best holiday destinations in the world (https://www.capetown.travel/).

2. Pre-Conference The conference was preceded by the Seventh African Young Geotechnical Engineers conference, the ISSMGE Board and Council meetings, as well as the International Geosynthetics Society (IGS) meeting.
